Notes OF Invention and Discovery from this
World Over.


drjcaI earthen vessel: pour three and one
third ounces OF commercial sulphuri
acid and one and three quarter ounces O
water into it, and then add one ounce o
powdered sulphate OF soda. In the cen
ter Of. this mixture place smaller vesse
containing toe wafer to be frozen; ther
cover the vessel and if possible revolvc
the whole with 8 gentle motion. In few
minutes the water in the smaller vessel
| will be converted Into Ice. The same
mixture can be used second or third
! time for making e block Of ice. The
operation should if possible be performed
in 2 cool place-in a cellar, for example,
lila Science en- Famiile,
A new electric submarine boat exhibited
at the recent Havre Maritime Exhibition
| is attracting the attention of scientists
It is something over eight meters in
length, two deep, and Of capacity of FIVE
tons. The shell is constructed entirely
OF steel. The stem and stern are fash
and full, but what is thus lost in speed,
in the opinion OF the inventor, is regsined
| in the greater safety of navigation.
The motive power is furnished by
dynamo electric machine invented by
| Captain Krebs of the French navy,
| famous for his dirigesble balloons, In use
now by the bsllooning corps of the army
The engine has ct times developed twelve
horse power. The energy Is stored in
| conservators, which contain neither LEAD
nor acids and which only weigh twenty
Kilograms for one-horse power, whereas
the storage batteries of the electric yacht
Volta weighed 100 Kilograms to each one
horse power stored. The boat has made
six sud one-half knots an hour for five
consecutive hours during the public trials
A remarkable secret has just been re-
vealed after burial II the sea for more
+airty.six years. On February l, 1851, a
submarine boat by Wilhelm Bauer was
sunk in the haroor of Kiel, where it re-
; NAMED in forty feet of water until lately
discovered in the course of dredging
operations. The curious craft has been
raised and its mechanism-kept secret by
it's inventor-has been exposed to view.
The boat was made of sheet-iron, and
was &c feet long, 10 deep and feet
wide. The driving was effected
by means OF 8 3-bladed screw
worked by two large wheels, each wheel
turned by man trsadiDg on projections
on it's periphery. The bow extended up
ward in peculiar shaped head provided
with bulls eyes closed by thick glass
Sinking and raising were effected by adj
hitting and pumping out water. The
boat was designed for placing torpedoes
under hostile vessels, end was success
fully tested, but was, unfortunately,
crushed by the pressure of the water at q
depth of thirty feet. It will be recon-
structed and preserved as the first ven
ture in submarine warfare.
DR.. Henry Hun has an article in the
Medical News on sewer poisoning, in
which he finds that no less than thirteen
classes of disease may be traced to the
inhalation-moTe or lees continued-of
the atmosphere from sewers. The list Is
as follows: Vomiting and purging, either
separate or combined; form Of nephritis
general debility, in some cases Of which
the heart is especially involved; fever,
which is frequently accompanied By
chills; sore throat, which is fire.
quently of diptheritlc character;
neuralgia; perhaps, also, myelitis
of the aterior horns; zYmotic dis
cases, such as typhoid fever, pneumonia,
diphtheria, cholera, dysentery, cerebro-
spinal meningitis, erysipelas and scarlet
fever Gin these cases undoubtedly the
sewer gas merely acts as vehicle for the
specific GERM; condition Of asphyxia,
which, in it's severe form, is character
lied By CONS, conv1lsions and collapse :;
puerperal fever, abcesses, lymphadenitis,
acute aural catsrrh( CD. The moral of ell
is this-lock 10 yoar plumbsge, and be
sure that there is an escape frota the
soilpipes, bathrooms, closets, etc, to the

It is often necessary to drive spike
under water in mill building or repairing.
The Manufacturers Gazette says; "One
of the best ways of effecting the desired
object is 10 get piece of steam pipe OF
sufficient siza to permit the spike to drop
easily through it. Place one end of this
pipe upon the spot where the spike is to
be driven, d-op the spike into the pipe,
point first, and hen follow Il with an iron
rod just large enough to slide easily in
the pipe. By using the iron rod as bat
tering ram, or like churn drill, the spike
can be easily and quickly driven home
without spettering the person with mud
and water. An Improvement on this spike
driving rig may be made by getting cast
iron ball OF two, four or six pounds
weight, drilling hole Trough the ball
sufficient to receive the iron rod, also
drilling another hole to receive set
screw. By screwing the set screw down
upon the rod the ball can be held in any
desired position. This ball gives extra
weighs to the driving rod, and, in fact,
forms kind of hammer whereby the
spike can be more quickly driven home.
1t will not work well il you try to drive
| the spike by means of the rod and q
sledge hammer. 1t is better, by all means
to rig up the ball above mentioned, which
Will do the WORK we'll and quickly"
The wonderful invention of WHITING BY
electricity at distance of fifty miles is
thus described by the Pail Mall Gazette
"Out Of the top Of box, which is about
the size Of an ordinary disp4soA box,
protrudes what has the appearance Of a
stylograrhic pen. This, however, is not
pen, but the handle of the transmit
ter" and its lower end is fxt
to q light brass perpendicular bar.
Any motion given by the hand-you
hold it just like pen-to the handle
OF the transmitter is communited by this
bar to two series of carbon disks con-
rained within the box, snd after various
adventures among magnets, etc, is car
ried again to the top Of the bnx, where it
is reproduced exactly by small ink
holding pen, whose point rests on q white
